WRAPPER-TRANSFERRING MECHANISM.

dent of Jersey City, county of Hudson, and

State of New Jersey, citizens of the United States, have inventedcertain new and useful Improvements in VVrapper-Transferring Mechanism,fully described and represented IO in the following specification andthe accompanying drawings, forming a part of the same.

i This invention relates to certain improvements in wrapper-transferringmechanism for wrapping-machines, and more particularly for 5 that classof wrapping-machines which are used to wrap cigars or cigar-bunches.

In wrapping cigars in which the wrapper is carried on a support and isdelivered to the bunch in the wrapping mechanism difficulty I has beenexperienced in properly positioning the end of the wrapper which isfirst wound on the bunch with respect to the bunch so that it may besecurely wound thereon by the wrapping mechanism. Devices haveheretofore 5 been employed in whlch the wrapper is carried on asuction,wrapper carr1er, a proper relative movement being producedbetween the carrier and the wrapping mechanism to deliver the wrapper tothe bunch or other article 5 to be wrapped, and in machines of thischaracter the end of the wrapper has been deliv- 1 ered to the bunch orother article in the wrapping mechanism by a blast of air, which blowsthe wrapper down upon the bunch, and also by tipping or bending down aportion of the supporting face of the Wrapper support. While thesedevices operate satisfactorily under some conditions, it has been foundthat under certain other conditions the end of the 4 wrapper is not sopositioned with respect to the bunch as to cause its end to be firmlyattached thereto at the beginning of the wrapping operation.

This invention has for its object to produce a wrapping mechanism forcigars or other analogous articles in which the wrapper is held on asupport and is then delivered by the support to the wrapping mechanism,a device being provided which positively engages the 5 vwrapper, takesit from the support, and delivers it to and holds it against the bunchin the .wrapping mechanism.

Specification of Letters Patent.

Application filed April 9, I904:- Serial No. 202,329.

Patented Jan. 2, 1906.

With this and other objects not specifically referred to in view theinvention consists in certain constructions and in certain parts,improvements, and combinations, as will be hereinafter fully describedand then specifically pointed out in the claims hereunto appended.

In the accompanying drawings, Figure 1 is a rear view of so much of awrapping mechanism having a preferred form of the wrapper-deliverydevice attached. thereto as is necessary to an understanding of theinvention. Fig. 2 is a detail elevation, partly in section, illustratingthe wrapper-delivering device in its relation to the wrapper-support.Fig. 3 illustrates the same construction as that shown in Fig. 2 withthe parts in different positions. Fig. 4 is a' sectional view on theline 4 l: of Fig. 3, and Fig. 5 is an elevation illustrating a detail ofconstruction.

Referring to the drawings, which illustrate one concrete embodiment ofthe invention, the improved wrapper delivery device is shown inconnection with a wrapper-carrier of the general type illustrated in thepatent granted to Patterson and Arents as the assignees of Oluf Tyberg.dated July 24, 1900, No. L203. While this illustrates a preferred formof construction, it is remarked that the wrapper-delivering device mightbe used with wrapper-carriers of adifferenttype.

The wrapping mechanism is marked 1, said mechanism being of the usualroller type, and therefore conventionally illustrated, the rollers beingdriven by a suitable train of gears 2 from any source of power. Anyother form of wrapping mechanism may be substituted for the rollermechanism here shown.

In the construction selected to illustrate the invention the wrapper isdelivered to the wrapping mechanism by means of a wrappersupport 3,which, as shown, is a suction-su pport. This support is mounted on acasting 4:, which is given proper movements to deliver the wrapper tothe wrapping mechanism. The particular construction by which thissuction-support is given its movements is unnecessary to anunderstanding of the invention; but in the preferred construction itwill preferably be substantially the same as that illustrated in thepatent hereinbefore referred to, and reference is accordingly made tosaid patent for a full disclosure of a proper means 'roo for effectingthe movements referred to. The casting 4 and the suction-support are incommunication with apipe 5, which communicates with a pipe 6, said pipeleading by suitable connections to a suitable suction-producingmechanism.

The device by which the wrapper is positively engaged, taken from thewrapper-support, and delivered to the wrapping mechanism may be Variedwidely in construction and will vary according to the particular type ofwrapping mechanism and the particular construction of wrapper-supportemployed. As shown, this delivery device consists of a finger having aflexible tip 7 formed of any suitable materialas, for instance, steelwireand a shank 8, to which the tip is secured in any desired manner.This finger may be operated and supported in any desired manner. Asshown, however, one of the stationary parts of the machine is providedwith a bracket 9, through which the rear portion of the shank 8 of thefinger passes loosely. The finger is further supported by a suitableguide, and in the preferred construction this guide will be madeadjustable, so that the finger may be properly directed in itsmovements. The particular construction of this guide may be variedwithin wide limits. As shown, however, it embodies a circular block 10,said block being provided with a conical recess 11, eccentricallylocated therein. In the construction shown this block is mounted in abearing formed in a standard 12, which is secured to the frame of thewrapping mechanism and which serves to support some ofthe shafts of saidmechanism. The block is held in position by a strap 13, the strap beingsecured by screws 14 in the usual manner. The shank of the finger isprovided in the particular construction shown with a conical collar 15.The movement of the finger may be produced by mechanism of any suitablecharacter. As shown,the shank passes through a perforation in a bent end16 of an operating-rod 17, this bent end lying between the collar 15,before referred to, and a second collar 18, secured to the shaft in anysuitable manner. This rod 17 connects with one of the arms 19 of abell-crank lever 19 20, said bell-crank lever being pivoted at 21 to theframe of the machine. The arm 20 of the bell-crank, as shown, isprovided with a roller 22, which at proper times in the operation of themachine is struck by a cam 23, carried on a cam-disk 24, mounted on oneof the cam-shafts of the machine. The

bell -crank is provided with a returningvious that the carrier must beformed in such a way as to enable the finger to get behind the wrapperin order to positively engage it. In the construction shown this iseffected by providing the carrier with a recess 27, which extends acrossthe carrier near its frontthat is to say, in the machine shown near theend of the carrier which carries the end of the wrapper which is to befirst presented to the article to be wrapped.

In the constructionshown, as before pointed out, the wrapper isdelivered to the wrapping mechanism by producing a movement of thewrapper-support. When the wrapper-support is swung into proper positionwith respect to the wrapping mechanismthat is to say, when the tuck endof the wrapper is over the tuck end of the bunchthe cam 23 strikes thearm 22 of the bell-crank 19 20 and throws the finger forward, theposition of the finger prior to the movement being that illustrated inFig. 2. As the finger moves forward the flexible end 7 enters the recess27, thus getting behind the wrapper on the wrapper-support, and thefurther movement of the finger causes the conical collar 15 to registerwith the conical recess 11 in the guideblock 12. As the conical collarregisters with the recess in the guide-block the finger is thrown down,as indicated in Fig. 3, and the tuck end of the wrapper is pressedfirmly onto the bunch and is there held. The wrapping mechanism nowcomes into operation and serves to wind the wrapper about the bunch. Atthe proper time and after the wrapping operation has begun thebell-crank slides off the cam 23 and the finger is retracted. It isobvious that by rotating the circular block 10 in its bearing the fingermay be give such adjustments as are necessary in order to enable it toproperly enterthe recess 27 of the carrier.

Changes and variations may be made in the construction by which theinvention is carried into effect. The invention is not, therefore, to belimited to the specific mechanism hereinbefore described, andillustrated in the accompanying drawings.
